BOTTLE CLOSURE.

Application filed November 10, 1921. Serial a. 514,408.

T 0 all whom it may cow/com:

Be it known that I, 'Fimncis H. Mums, a citizen of the United States, residing at Boston, county of Suffolk, State of Massachusetts. have invented a certain new and useful Improvement in Bottle Closures, of which the following is a specification, referonce being had therein to the accompany-.

in drawings. I

he invention relates to stoppers 'or closures for bottles and similar containers and has for its object a closure which can be readily applied to or removed from the bottle or other container. It 1s especially intended for-use with a bottle m which the closure or stopper is to be repeatedly removed for the purpose of taking out a part of the contents and replaced to close the bottle again. lhe special-object of the invention is to'provide a stoppdr of such charbe readily tightened up after itis applied to the bottle and maintained in its tightened position until ready to be 0 ened and then the closure can be readily oosened in order to permit it to be easily removed from the bottle.

The invention will be fully understood from the following description when taken in connection with the accompanying drawn" ings, and the novel features thereof will be pointed out and defined in the claims at,

the close of this specification. i

In the drawings, Fig. 1 is a plan now of a device-embodying the invention as applied to a bottle.

Fig. 2- is a section on line 2--2 of Fig. 1.

Fi 3 is a side elevation of the device, detac ed from the bottle.

Fig. at is a plan view of the closure memher before being gonnectied with the clampin member. s

i'g. 5 is a side elevation of the metallic I disk which is to be used with the cushion bers, namely, a stopper pad.

Fig in F1 5. I

Referring now to the drawings, at'1 is shown the upper portion of a bottle having a rim orbead 2 around the top of the neck of well-known form ofconstruction. The device embodiesessentially two main memor'cap member A 6 is a plan view of the disk shown and alclampingmemberiB. The stopper member A consists of a 'cap 3 having a downwardly extendingerip'heral flange .4, thus. forming a sort" 0 a cup in. WhlCll is seated a compressible cushion 5, preferably of rubber, made in the form of a disk is provided a metallic disk 6 introduced between the mslde face of the cap and therubber cushion, this disk being formed with a downwardl I extending nub 7 a in the mid dle, which w ien the closure is placed upon the bottle and tightened up, as hereinafter .descnbed, causes a downwardly extending bulge 1n the rubber pad 5 whichenters the neck of the bottle.

' The cap formed with an upwardly extending cylindrical nub or hub 10 on its upper surface for pivotal engagement with the clamping member B, as will be presently described.

The clamping member B is formed preferably w th a disk-shaped head portion 11 having a central aperture 12 through which the hub 10 looselypasses, so that the clamv mg member may-be rotated thereon. '1 1e said clamping disk 11 is )rovided with two clamping fingers 1313 iametric'ally oppos te each other extending from the opposite sides of the periphery of the said disk 11, said clampin fingers being curved out wardly and then reversely curved forming the bowed lips 14: which extend inwardly somewhat farther than the lower edge of the flange 4 of the cap member. These lips 14 are ada ted to engage with the annular groove 15 ormed in the neck of the bottle" under the top bead 2. The width of the ber' there are formed a lurality of inolined faced cams 17, pro? number, each being arc-shaped in plan view and arranged .in acircle which. is concenerably three in trio with the closure member. The under face of the' disk 11 of the olampin member'is formed with aplurality of downwardly extending lugs 18 corres onding' in nmnber' with the cam surfaces .17, so that when the clam'pin member is rotated with relation tothe closure member, the said covers the device whether used with or lugs will ride up on the: cam surfaces and depress the closure member. When the device is applied to'the bottle, the closure member rests on top of the neck and the clamping fingers engaged with the groove 15 on the under side of. the head of the bottle,

while the downwardly extending lugs on the clamping member are free from the cam surfaces; and then by rotating the clamping member to cause the said lugs to ride up on the cam surfaces, the closure member will be drawn down tightly onto the rim of the bottle and if it is tightened up as far as it will go it will hold the cap firmly against the top of the bottle. Preferably there are provided stops 19 at the top of the cams to limit the turnlng movement of the clamping member B.

Preferably the flanged closure disk is stamped out of a piece of metal in such manner as to also stamp out the upwardly projecting hub member 10, and also to form the cam surfaces 17, although this is not essential to the invention. Preferably also the lugs 18 on the clamping member are formed integral with the clamping member. 1

While I prefer to employ the disk 6 with the projecting bulge 7, said disk may be entirely omitted and my invention broadlv without said intermediate metal disk 6. o

What I claim is: 1. A bottle closure havinga cap member to go over the top of a bottle, and a clamping member rotatably mounted on the upper side of the cap member and slightly movable axially withrelation thereto, the clamping member being provided with means for engaging the beaded rim of a bottle, the proximate surfaces of the clamping member and the cap member being provided one with,

cam surfaces and the other with projections which engage said cam surfaces, whereby the rotation ofthe clamping member causes the said projections to ride.up on the cam surfaces and tightly clamp the said cap'to the top of the bottle. v

2; A bottle closure having a cap member to go over the top of a bottle, and havinga. pad therein to engage the top of the bottle,

a' disk between said pad. and the cap having a protuberance whiph engages the middle of said pad. a clampin member rotatably mounted on the upper side of the cap member and slightly movable axially with relation thereto, and means whereby the clamping member may,-when rotated, move the cap member awa therefrom to crowd it down tightly agalnst the rim of the bottle and thereby also crowd said protuberance on the disk against the pad and cause the pad to bulge downwardinto the neck of the bottle.

' the cap being A bottle closure having a cap member to go over the top of the bottle having a flanged rim and a flexible pad seated therein, the cap being provided withan upwardly extending hub on its upper surface, and a plus ra-lity of cam surfaces also arranged on the upper surface concentrically about said hub, and a clamping member consisting of a disk having a central hole through which said hub on the closure member extends and in which the said hub is rotatable, the clamping member having peripheral fingers which extend downwardly to engage the bead on the upper end of the bottle, said clamping member having on its under side projections which are adapted to engage with the cam surfaces of the closure-member, whereby the. cap member is clamped tightly against the top of the bottle.

4. A bottle closure having a cap member to go over the top of the bottle having a flanged rim and a flexible pad seated therein,

provided with an upwardly extending hub on its upper surface, and a plurality of cam surfaces also arranged on the uppersurface concentrically about said hub, and a' clamping member consisting of a disk having a central hole through which said hub on the closure member extends and in which the said hub is rotatable, the clamping member having peripheral fingers which extend downwardly to engage-the head on the upper end of the bottle, said clamping member having on its under side projections which are adapted to engage with the cam surfaces of the closure member whereby the top of the bottle and clamped thereto.

6. Abottle' closure comprising a cushion cap member, a clamping member rotatably mounted on said cap member and having a slight axial movement with relation thereto, said two members being provided with interengaging -cams whereby when the clampingmember is rotated with relation to the cap the cap is tightly drawn against the top of thebottle and clamped thereto, and stopswhich limit the rotary movement of the clamping member.

I In testimony whereof I afiix my signature.
